SHOE RAND CEMENTING MACHINE Filed June 5 ;927 2 Sheets-Sheet 1 Patented Oct. 22, 1929 UNITED STATES PATENT OFFICE JOHN W. GOSGROVE, OF MEDFORD, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY SHOE-RAND CEMENTING MACHINE Application filed June 30,

This invention relates to rand treating machines and is illustrated as embodied in a machine for cementing either horseshoeshaped or straight rands.

The beveled strips of material which are used in the manufacture of shoe rands vary greatly as to quality so that some are comparatively firm and semi-rigid strips, while others are of very flimsy material and have :oft irregular edges, especially at the thin edge. Frequently, too, the strips become distorted between the time that they are cut and the time when they are taken out for use so that, in transverse section, instead of being in the form of a right-angled triangle, they are curled transversely. Such strips, if dry and stiff, are somewhat difficult to handle, especially when presented for treatment, as to a machine for applying cement to one surface of a randstrip.

Accordingly, one object of the invention is to provide an improved machine for treating beveled rand strips wherein the handling of the strips will be greatly facilitated regardless of their characteristics and particular shapes.

To this end, the illustrated machine is provided with a cement-applying roll having a concave periphery so that even though the strip may have curled transversely it will be possible to apply cement evenly to the whole width of one surface of the curled strip. Cooperating with this applving roll is a presser roll havinga periphery convex in transverse cross-section, one end face of which is larger in diameter than the other end face. This larger portion of the illus trated roll is arranged to contact with the thinner edge of the beveled strip therebyto press it firmly into contact with the face of the applying roll. Divergent guides are preferably provided to facilitate the introduction of the ends of rands, especially the flimsy ones, into the machine. 7

' Some rands, known to the trade as turned rands, are formed into approximately horseshoeshaped strips of material and in the presentation of such strips to a treating machine, it has been necessary for the operator to hold on to the strips and turn 1927. Serial No. 202,539.

them so as to present the whole length, including the curved closed ends of the horseshoe-shaped strips and the two sides, to the action of the machine.

Accordingly, another object of the invention is to provide a machine by the use of which treatment of horseshoe-shaped strips of material will be facilitated. To this end, the illustrated machine is organized to guide such a stripautomatioally through the ma chine after one end thereof has been taken up by the feeding mechanism.

In accordance with another feature of the invention, a machine having feeding means urging the strips forward in a straight path, is provided with a guide which is disposed laterally of the path of movement of the strips and which is arranged to contact with the inner rim of each horseshoe-shaped strip, thereby to turn it around so that the whole length of each strip will be fed automatically through the machine.

In the drawings,

Fig. 1 is a perspective view of a rand cementing machine embodying the invention;

Figs. 2 and 3 are plan views of the apply ing roll of the machine and the guides, showing the action of the machine in guiding a horseshoe-shaped strip of material automatically to the applying roll:

Fig. 4 is a side elevation, with parts broken away and in section, of the machine shown in Fig. 1; and

Fig. 5 is an enlarged section through the coacting rolls and an interposed rand strip.

The operating parts of the illustrated rand cementing machine are mounted upon a base 10 at one side of which there is provided a drive pulley 12 which is connected through gears 14. and 16 to a presser roll 18 and a treating roll 20 mounted on shafts 15 and 17 respectively. This treating roll 20 is a cementapplying roll and is journaled in a cement receptacle 22 having a supply reservoir 24, the receptacle being pivotally mounted upon a pin 26 and urged upward to grip the work by means of a spring 28 within the base 10. The tension of this spring may be adjusted by a hand nut 30 and the upward movement of the roll is limited by a stop screw 32. The

amount of cement taken up by the roll may be controlled in any suitable manner, the illustrated machine being provided with an adjustable scraper 3& for this purpose.

In order to adapt the machine especially for the treatment of beveled rand strips roll 1S,, which, as may be seen from Fig. 3,

is provided with a periphery whichis convex in transverse cross-section and s made larger at itsouter end 44, than it 1s at its inner end 4L6. The larger end 44 is made to coact with the thinv edge of each rand strip 40 while the smaller inner end coacts with the thicker edge to hold the whole width of the strip in contact'with the treating roll. It is notnccessary that the transverse cross-section of this presser roll shall exactly correspond to the transverse cross-section of the upper side of any particular thickness of, the beveled strip as it'rests on the treating roll as the presser roll must coact with various sizes of strips and the naturalresistance to deformation of the strip will helpto hold down the strip at the edges -when the presser roll 18 acts along the middle.

The combinedaction of the rolls 18 and 20 upon the strip is to urge it forward in a straight path and the guidance ofstrips presentedto the machine is facilitated by the use of a flat-faced guide member having a supporting stud 52 by means of which it is ad justably supported upon a lug 5a forming part of the receptacle 22. The stud 52 is held on the lug 54 by means of a clamping screw 56.

The presentation of beveled rand strips to the machine is still further facilitated by the provision of guide flanges and 62 extending outwardly from the face of the guide member 50 at its forward portion. As may be seenby an inspection of the drawings, these guide flanges 60 and 62 are so related to one another that they diverge outwardly towardrthe front of the machine, thus forming an open mouth to which it is easy to presentthe advancing end of each strip, thereby to locate the strip eXactlybetween the bite of the rolls. The guide flanges GO and 62 are also disposed in divergent directions transversely of the pathof feeding movement so thatfthey converge near the outer'edge of the rolls andform a. triangular-shaped opening corresponding approximately to the crosss'ectional shape of the beveled rand strips. These guide flanges are found especially desirable when the machine is to be used for rand strips which are soft and flimsy and aid the operator in feeding the strips correctly to the machine so that they will not be diverted from between the rolls and passed diagonally out of the machine without receiving proper treatment.

When the machine is to be used for cementing horseshoe-shaped turned rand strips 70, the approximate shape of which is illustrated in Figs. 2 and 3, then a guide 72 is provided wnich is disposed laterally of the path of movement of the strips and for\ 'ardly of the axis of the rolls for engagement with the inner rim 74 of each of the horseshoe-shaped strips of material. This guide 72 is pivotally mounted in a bracket 76 and its position transversely of the path of movement of the strips may be determined by means of a hand screw 78 acting in opposition to a spring 80 insertcd between the bracket 76 and the guide 72.

T he action of the guide 72 is to contact with and exert a drag upon the inner rim 7a of each of the horseshoe-shaped strips 70, thereby automatically to turn it as it is pulled forward by the feeding means so that after one of the open ends of the horseshoe-shaped strips has been presented to the machine and its feeding movement started, the machine will treat first one of the straight sides, then the closed curved end of the strip, and then the other straight side without interference upon the part of the operator, this action being illustrated in Figs. 2 and 3. It will be understood that the guiding action of the guide 72 is effective either with or without the guide 50 and the flanges 60 and 62, although in the preferred form of the invention, these guide flanges and the fiat-faced guide member 50 are combined with the guide 7 2 and all work together to make a machine which is semiautomatic in its operation and which allows the treatment of a large number of horseshoe-- shaped strips of material in a short time without reducing the quality of the work produced.

It will be understood also that, in various respects, the invention is not limited to embodiment in the particular type of machine shown and described or to the performance of the particular operations referred to. The scope of the invention should be determined by the accompanying claims, giving the broadest construction to the terms of the claims which is permitted by the prior art.
